The Culverwell Mineral property is an established gold and silver mine located in Lincoln County, Nevada. The mine has limited documentation of production but shows average values of 1.44 oz/T AU and 2.31 oz/T AG. The mine was located by Mr. Charles Culverwell and Mr. William Culverwell in 1899. The mine was re-located by two miners in the resurgence of 1932 and documented production of 5 tons of ore containing 7.2 ounces of gold and 11.5 ounces of Silver.
The mine is noted for production of wire gold in iron and on quartz. Surveyors did not witness any wire gold, however, surveyors reported multiple instances of small gold deposition in the short offshoots of the haulage tunnel and some high-grade gold samples were removed from the main working room/stope.
Mining Claim Description
The mine has at least three portals which intersect the Culverwell workings and are reported to interconnect via winzes and raises. The two upper portals have collapsed or been backfilled and are not accessible as of 2018. The primary Culverwell Adit is in good condition and accessible. It is secured by a large iron gate and reinforced with timberwork.
At the base of the mountain, below the mines is the Culverwell Camp or History Repeats camp as it has also been known. The camp is quite extensive and a testament to the workings of the mine. A large, 3-bedroom house has been laid out with a kitchen, dining room and an upper level workshop. The majority of the cabin has been utilized for processing of the gold and there are various mining implements, tables and separation vats in the house.
There is a carport outside the house with concrete foundations and room for at least 3 full size vehicles. In addition, there is a large cistern (assumed 5000 gallon) attached to the house, fully concreted and above ground. Other indications of habitation at the site include chicken coops, outhouses and various outdoor tubs with exposed plumbing. There is an inscription on the concrete near the cistern which reads “History Repeats”.
Waste Dumps at the mine were sampled and showed calcite, quartz, pyrites, raw gold, some silver and iron with likely tungsten and or molybdenum.
The accessible workings in the mine consist of a haulage tunnel with some short offshoots and a stoped room where a gold ore body appears to have impacted a dike. There is a small headframe a winze of approximately 30’. At the bottom of this winze, there is an apparent drift cutting back on the same ore deposit as above. The lower level was not mapped or examined but it said to intersect with the workings of the upper two adits through a series of raises and other drifts. This information is unverified.
In addition to the lower levels, also noted was a potential raise near the headframe, the passageway was extremely narrow and was likely an ore chute at one time, however, it is possible to attempt access to upper levels through this raise.
28 lbs. of high-grade gold ores were sent for assay and returned a value of 22.9 oz/T in AU with only trace silver. This indicates that the gold deposits, when kept in a pure form have very little silver or other contaminants and could be crushed and washed as a way of processing with no chemicals needed. It also indicates that working specifically on the veins which are showing gold deposition within the mine would be the most lucrative plan for a small miner or mining company.
